Fitting and visualizing models [model]

(Builds on: Exploratory data analysis (2D), Model basics)
(Leads to: Models with multiple variables)

It is possible to understand some models (particularly popular statistical models) by learning how to interpret their coefficients. We’re not going to take that approach here for two reasons:

Instead, we’ll understand a model by looking at it’s predictions. This doesn’t cover every possible type of model (because not every model makes predictions) but it does cover a very wide class, including most models in statistics and machine learning.
